UNITED STATES ARNOLD L. OGDEN, OF NEW YORK, N. Y.

FOUNTAIN-PEN.

Specification of Letters Patent.

Application filed December 4, 1919. Serial No. 342,319.

To all whom it may concern:

Be it known that LARNOLD ii. OGDEN, a citizen of the United States of America, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a full, clear, and exact description.

This invention relates to improvements in self-filling fountain-pens of the lever type, the object being to provide a novel inexpensive but efficient mechanism to compress an ink sack or reservoir. My invention is directed mainly to the improvement of the sack compressing device from the structural point of view, the elimination of certain steps in the formation of the device be ing effected, besides simplification thereof.

1 will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawing, wherein- Figure l is a sectional view, partly in elevation, of a pen embodying my improvements;

Fig. 2 is a perspective view of a part of the frame;

Fig. 3 is an enlarged fragmentary sectional view illustrating one end of the frame, a portion of the sack compressing lever and associated yieldable shoe.

Fig. 1 is an enlarged fragmentary sectional detail View;

Fig. 5 is a fragmentary plan view of a portion of the blank out of which the frame is formed; and

Fig. 6 is a side view of a modified form of my invention.

In the drawing a fountain-pen barrel is indicated by 7, a pen section by 8, and a depressible sack or reservoir by 9, all of which are well known elements in self-filling fountain pen construction. My invention is directed to the improvement of the frame 10 which supports the sack depressing lever 11. To simplify the manufacture and improve the construction of said frame I form same out of a single strip of material. The frame consists of a body portion 12 turned over at one end as at 13 to form a po'ketto receive the curved end 14: of a yieldable shoe 15 which bears against the sack 9. Intermediate its ends the body portion 12 is turned up to provide flanges 1 1' between which depressing lever 11 is pivotally mounted, by

means of a pin 18. To permit depression of Patented Feb. 8, 1921.

the sack by the lever, the frame 10 is provided with an opening 19 through which the lever projects or rather the heel 20 of the lever. To stiffen the bar 9 I provide the channel, formed by the flanges 1 1 with an end wall 22, said end wall having a projecting tongue 23 between the shoe 15 and adj acent portion of the barrel 7.

The end wall 22 and tongue 23 are integral with the material of the frame 10. The frame 10 is formed out of a blank 24 (Fig. 41) having wings which are turned up to form the flanges 14 and a projection or extension which is turned up to form the end wall 22 and tongue 23, as indicated in Figs. 3 and at. The blank 24 is of course provided with the opening 19. In conjunction with the frame I employ the yieldable shoe which when lever 11 is moved to a vertical position depresses sack 9 to exclude air therein. Upon release of the lever, or movement thereof to the horizontal position, the sack will fill. The end wall 25 of opening 19 acts to limit the movement of lever 11 when said lever is operated to compress the sack.

Instead of forming the frame and yieldable shoe out of two separate strips, I may form the same out of the same strip, as indicated in Fig. 5. In this latter instance the blank 24: will be long enough to permit of its being bent over upon itself intermediate its ends to form a yieldable shoe 26. The turning over of the frame at its end 13 in the form illustrated in Fig. 2 provides a yie1dable finger 27 which acts to maintain the presser-bar in position within the barrel. Nhen formed as indicated in Fig. 6 the device will be provided with a yieldable finger 28 to maintain it in position within a barrel. The barrel 7 will be provided with a slot or opening 29 for the reception of the flanged portion of the frame 10, which is held in position in the slot by pressure.

Having now described my invention, what I claim is:

1. A lever supporting frame for self-filling fountain-pens consisting of a body portion bent upwardly along a portion of the sides thereof to provide flanges for the formation of a channel, said body portion being bent up at one end of said channel to form an end wall, thence downwardly and outwardly to provide a tongue, and a lever pivotally mounted in said channel.

2. A lever supporting frame for self-filling fountain-pens consisting of a body portion bent upwardly along a portion of the sides thereof to provide flanges for the formation of a channel, said body portion being bent up at one end of said channel to form an end wall, thence downwardly and outwardly to provide a tongue said body portion being provided'with an opening therethrough, said opening being located. between said flanges, and a lever pivotally mounted. between said flanges and projecting into said opening.

3. The combination of a lever supporting frame for self-filling fountain-pens and a 15 Signed at New York city, N. Y., this 25 20 day of November, 1919.
